CSS Margin
Margin
The margin clears an area around an element (outside the border). The margin does not have a background color, and is completely transparent.
The top, right, bottom, and left margin can be changed independently using separate properties. A shorthand margin property can also be used, to change all margins at once.
Possible Values
Value Description
auto The browser calculates a margin
length Specifies a margin in px, pt, cm, etc. Default value is 0px
% Specifies a margin in percent of the width of the containing element
inherit Specifies that the margin should be inherited from the parent element
Remark It is possible to use negative values, to overlap content.
Margin - Individual sides
In CSS, it is possible to specify different margins for different sides:
Example
margin-top:100px;
margin-bottom:100px;
margin-right:50px;
margin-left:50px;
Margin - Shorthand property
To shorten the code, it is possible to specify all the margin properties in one property. This is called a shorthand property.
The shorthand property for all the margin properties is "margin":
Example
margin:100px 50px;
The margin property can have from one to four values.
margin:25px 50px 75px 100px;
top margin is 25px
right margin is 50px
bottom margin is 75px
left margin is 100px
margin:25px 50px 75px;
top margin is 25px
right and left margins are 50px
bottom margin is 75px
margin:25px 50px;
top and bottom margins are 25px
right and left margins are 50px
margin:25px;
all four margins are 25px
